RFA

High power, single-frequency, CW Raman fiber amplifier
Our highly reliable Raman fiber amplifiers (RFA) are based on patented technology. With their high power of up to 30 W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fiber amplifiers. The RFA is designed using TOPTICA’s high quality engineering excellence and utilizing a stable European & North American supply chain. The all fiber design requires no re-alignment and provides a high degree of stability. The RFA offers a wide tuning range of up to 10nm, a relative intensity noise <1% RMS (10 Hz- 10 MHz) and excellent long term RMS power stability of less than 0.5 % over 100 hours (with a TA pro seed laser).
The RFA is utilising the proven and stable DL pro or TA pro as a seed laser, enabling a seamless integration into the TOPTICA environment of for example wavelength stabilization options. 
The system consists of two modules:
  • The Fiber Pump Module: Providing pump light for the RFA module
  • The Raman Fiber Amplifier Module: High power amplifier module with inputs from the pump module and the seed laser

Your Benefits

High power from 1120 to 1370 nm
High power of up to 30 W where normal fiber amplifiers cannot reach. 
Wide tuning range
Tune widely, with up to 10 nm tuning range. 
Reliable and maintenance-free
High reliability and maintenance-free platform design. The RFA is designed using TOPTICA’s high quality engineering excellence and utilizing a stable European & North American supply chain. 

Applications

Quantum physics science
Quantum computing & simulation
Quantum communication
Quantum sensing & metrology
Lithography & microfabrication
Semicon inspection & metrology

Options

Frequency doubling
To reach visible wavelengths the RFA can be integrated with TOPTICA 's SHG portfolio of frequency doubling systems. With these, high power in the visible wavelengths (for example more than 15W at 589nm) can be achieved while maintaining tunability over the entire RFA tuning range.
Frequency quadrupling
To reach UV wavelengths the RFA can be integrated with TOPTICA 's FHG portfolio of frequency quadrupling systems. Drawing on TOPTICA’s extensive experience of custom (D)UV systems and maintaining tunability over the entire RFA tuning range.
Additional wavelengths
For wavelengths outside this range please enquire for a custom system.
Third party seed laser
Utilizing a third party seed laser of your choice is possible. Please inquire for requirements.
